Operating Instructions
The RAINBOW Model E2 Type 12 offers two operating speeds and various attachments for different cleaning tasks.
Powering On and Speed Control:
- To turn on the unit, press the power button (usually indicated by 'I' or a power symbol).
- The unit has 2 power levels. Use the control method (touch/push button) to select the desired speed. Lower speeds are ideal for air purification, while higher speeds provide maximum suction for vacuuming.
Using the Power Nozzle:
- Attach the power nozzle for carpet cleaning. The LED lighted water basin and power nozzle brush illuminate the cleaning path, enhancing visibility.
- The power nozzle features rotating edge brushes that effectively clean along baseboards and in corners, ensuring no spot is missed.
- Guide the power nozzle slowly over carpets for optimal dirt and debris collection.
Air Purification Mode:
- When not actively vacuuming, the unit can function as an air purifier. Operate it on a lower speed setting to quietly circulate and clean the air in your room.
- The water filtration system traps airborne particles, dust, and allergens, providing cleaner air.
Using Other Attachments:
- Dusting Brush: Ideal for delicate surfaces, furniture, and blinds.
- Crevice Tool: Perfect for narrow spaces, corners, and edges.
- Upholstery Brush: Designed for cleaning upholstery, curtains, and other fabric surfaces.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your RAINBOW cleaning system.
Water Basin Cleaning:
- After each use, always empty and clean the water basin. Dispose of the dirty water responsibly.
- Rinse the basin thoroughly with clean water. You may use a mild detergent if necessary, but ensure it is completely rinsed out.
- Allow the water basin to air dry completely before reassembling or storing the unit to prevent mold or mildew growth.
HEPA Filter Maintenance:
- The unit is equipped with a HEPA Exhaust Filter. Refer to the manufacturer's guidelines for recommended cleaning or replacement intervals for the HEPA filter.
- Periodically inspect the HEPA filter for excessive dirt buildup. A clogged filter can reduce suction power and air purification efficiency.
General Cleaning and Storage:
- Wipe down the exterior of the main unit and attachments with a damp cloth.
- Ensure all components are dry before storing.
- Store the cleaning system in a cool, dry place away from direct sunlight.
- For optimal performance and to prevent clogging, it is recommended to periodically turn the main unit upside down and clean the plastic filter with a wrench or pliers and a toothbrush.
